At present, world's photovoltaic generation industry with the development of about 28% annual speed, is being one of the fastest industry of world development just.In the various available solar energy batteries of prior art, though adopt the non-crystal silicon solar cell of glass or plastic base the most cheap, efficient only is about 6%; And adopt the efficient of the multi-junction gallium arsenide solar cell of single crystal wafers can be up to 30%, yet cost be the former 100 times; There is the shortcoming that technology is unstable and generating efficiency decays in thin-film solar cells, and battery life is short; Monocrystalline silicon and polysilicon solar cell are modal types, and its efficient is 10-18%.Currently cause the higher polycrystalline silicon raw material of original cost to go up to more than 140 dollar of per kilogram in 2007 owing to be the demand multiplication of the solar power generation product of raw material to polysilicon, the price that causes generating electricity also reaches 4.1 dollars every watt.This shows that because of existing solar cell exists cost higher relatively, conversion efficiency is low, factors such as technology instability are so hindered the solar photoelectric broad application.Therefore, improve photovoltaic efficiency in the coming years, reducing cost is the direction of solar power generation industry development.
The concentrating solar battery The Application of Technology can be avoided the construction method of technical sophistication, excessive risk, high energy consumption to a certain extent, improves the generating rate.The kind of concentrating solar battery can be divided into transmission optically focused and reflecting condensation by principle.Patent publication No. be CN1434257A's " comprehensive concentrating solar energy-collecting device ", this device to corresponding with it reflective mirror, is projected anaclasis on the energy collecting jar by the collector lens of band sun tracker again.Though having solved, it utilize direct sunlight efficient low, can't be in time and the problem of season from motion tracking, and it exists the optically focused spot intensity inhomogeneous, processing difficulties, the cost height, device shaped is not easy to the shortcoming of large scale application.Patent announcement number is CN2882109Y " a butterfly solar reflecting and condensing device ", and the mirror reflects sunlight that this device is symmetrical in center line by four row makes reflective mirror towards sunlight by auto sun-tracking system to the solar battery array of a corresponding side.It has saved the use of convex lens, but its solar cell can block the part sunlight that shines on the speculum, and exists sun tracker cost height, device shaped to be not easy equally and build the shortcoming that combines.Patent publication No. be CN85101607A's " solar energy concentrator with flat side-mirrors ", this concentrator is by the non-imaging concentrator of the flute profile of symmetry, the reflecting wall of every side is rearranged from top to bottom by one side or the above plane mirror of one side.It need not the symmetrical non-imaging flute profile concentrator of Continuous Tracking, and cost is lower.But it is subjected to the variable effect of solar angle degree bigger, need be with the elevation angle of regulating concentrator season; Optically focused is not than being optimized to optimum efficiency, and the unit are light income is little; If solar panel is arranged in the bottom of groove by its method, the solar panel partial short-circuit that causes, and influence generating effect may take place because uneven illumination is even in the burnt out-of-shape of spot.This patent does not have to set forth combination how to optimize solar panel in addition, improves the generating efficiency of solar cell.
Summary of the invention
The purpose of this invention is to provide a kind of condensing solar power generation plate reflected from composite parabola, its reasonable in design need not solar tracking system; significantly increase the energy output of unit are solar cell, improve generating efficiency, it is easy to manufacture; easy construction; safe in utilization, its template is close with existing sheet material specification, the assembling flexibility and reliability; can substitute existing roof panels and sunny side exterior wall; cost is low, can large scale application, help environmental protection and energy savings.
The object of the present invention is achieved like this: this power generation plate comprises framework and assembles its interior face shield, optically focused reflector and solar panel, its technical essential is: described optically focused reflector is made up of matrix and light reflecting membrane that the cross section is the smooth concave curved surface of compound parabolic, matrix bottom opening place's sealing-in solar panel, each optically focused reflector of array distribution closely is arranged in the described framework, and the solar panel of each matrix bottom joins by lead and through inverter and controller and electric power system.
